The provenance of these files is explained by this quote: "...It was at this time that Fr. Abraham took on the task of recording the entire Tanak in Hebrew. Fr. Abraham always showed a great passion for the Hebrew language and often chided his young fellow Israelis for not speaking Hebrew well....The diffusion of the audio recordings has been entrusted to the Carmelites in light of Fr. Abraham’s devotion to St. Theresa of Lisieux. The original tape recordings were transferred to digital audio by Audio Scriptures International, and then transferred to mp3 files, divided according to chapters, by the Academy of Ancient Languages. These latter mp3 files are used in this rendition of the Hebrew Tanak."
Metadata has been added to these files to make them easier to use on mobile devices, but they are otherwise unaltered from their source.
None of these sites make any copyright claims, but their wording (i.e., no commercial redistribution) seems to suggest rights analogous to those of a Creative Commons license, which has been added here.
